According to our understanding, the CCTV monitoring system is an important part of the security technology prevention system. Cisco 400-051 is an advanced integrated system with strong prevention ability. It can remotely control the camera and its auxiliary equipment (lens 350-018 Lab 350-018 Lab The technical requirements of the CCTV monitoring system are mainly: the clarity of the camera, the transmission bandwidth of the system, the signal-to-noise ratio of the video signal, the format of the TV signal, and the camera. Its transmission medium is video cable. Simulated processing by the control host. Mainly used in high-end places such as banks and government agencies.

The video surveillance business has a long history and has traditionally been widely used in the security field. In recent years, with the rapid development of digital image processing technology and digital circuit technology, the digitization and processing of image signals have become more common, and the use of digital image processing technology for dynamic monitoring and on-site monitoring has become a reality, and it has a relatively high sensitivity. and reliability. Video surveillance system is widely used in many fields such as financial system, transportation system, public security system, education system and medical system for its intuitive, convenient and rich information content. The traditional video surveillance technology no longer meets the needs of the development of the times, and the network video surveillance system based on computer and network communication technology and featuring intelligent image analysis has gradually become the development direction of the surveillance field.

At present, the large-scale network video surveillance business is still in the initial stage of exploration. Networking, digitization and intelligence are the inevitable trends of video surveillance. For this general trend, the current video surveillance has many deficiencies in some key technologies. It is mainly manifested in video storage, concurrent scheduling, billing, hierarchical business integration and so on.
